Abstract

An illustrative example embodiment of an elevator system includes a cab configured to accommodate at least one passenger or item inside the cab. A motorized module includes a base, a connector supported on the base and at least one drive member supported on the base. The connector is configured to selectively establish a releasable connection between the motorized module and the cab. The drive member is configured to engage a vertical surface, climb along the vertical surface to selectively cause vertical movement of the base, and selectively prevent movement of the base when the drive member remains in a selected position relative to the vertical surface. At least one motor is associated with the drive member to selectively cause the drive member to climb along the vertical surface. The motorized module is vertically movable independent of the cab when the motorized module is released from the cab.
